#region 将List转换为Json public string List2JSON(Listobjlist) { string result = ""; result += "["; bool firstline = true;//处理第一行前面不加","号 foreach (object oo in objlist) { if (!firstline) { result = result + "," + OneObjectToJSON(oo); } else { result = result + OneObjectToJSON(oo) + ""; firstline = false; } } return result + "]"; } private string OneObjectToJSON(object o) { string result = "{"; Liststring> ls_propertys = new Liststring>(); ls_propertys = GetObjectProperty(o); foreach (string str_property in ls_propertys) { if (result.Equals("{")) { result = result + str_property; } else { result = result + "," + str_property + ""; } } return result + "}"; } private Liststring> GetObjectProperty(object o) { Liststring> propertyslist = new Liststring>(); PropertyInfo[] propertys = o.GetType().GetProperties(); foreach (PropertyInfo p in propertys) { propertyslist.Add("\"" + p.Name.ToString() + "\":\"" + p.GetValue(o, null) + "\""); } return propertyslist; } #endregion
将DataSet中数据表的内容转成list
DataSet ds = bll.GetList(0, "", "add_time asc"); Listmodels = new List (); if (ds == null || ds.Tables.Count 0 ) return null ; DataTable dt = ds.Tables[0]; for (int i = 0; i ) { //创建泛型对象 Model.fivestarsore model2 = Activator.CreateInstance (); //获取对象所有属性 PropertyInfo[] propertyInfo = model2.GetType().GetProperties(); for (int j = 0; j ) { foreach (PropertyInfo info in propertyInfo) { //属性名称和列名相同时赋值 if (dt.Columns[j].ColumnName.ToUpper().Equals(info.Name.ToUpper())) { if (dt.Rows[i][j] != DBNull.Value) { //if (info.PropertyType == typeof(System.Nullable )) //{ // info.SetValue(_t, Convert.ToDateTime(dt.Rows[i][j].ToString()), null); //} //else //{ info.SetValue(model2, Convert.ChangeType(dt.Rows[i][j], info.PropertyType), null); //} //info.SetValue(_t, dt.Rows[i][j], null); } else { info.SetValue(model2, null, null); } break; } } } models.Add(model2); }
